A compound Z with molecular formula `C_(3)H_(9)N` reacts with `C_(6)H_(5)SO_(2)Cl` to give a solid, insoluble in alkali. Identify Z.

Explanation

`Z(C_(3)H_(9)N)` is an aliphatic amine. On reaction with `C_(6)H_(5)SO_(2)Cl` (Hinsberg's reagent), It gives a product insolude in alkali. It means that the product does not have a replaceable H-atom attached to the N-atom. So, compound Z is a secondary amine(ethyl methyl amine).
